Why Multistage Pumps Are Best For Boiler Feed Applications

Multistage centrifugal pumps are a popular choice for boiler feed applications, but what makes them the better choice? All centrifugal pump curves show a decrease in pressure as flow increases. With single stage pumps, this means that a larger pump is needed to increase the pressure

Boiler feed pump KSB

Boiler feed pump Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted.

Two Aspects of Deciding Between A Ring-Section and A Barrel Pull-Out Pump Are Described Below1. The smaller the mass flow rate and the higher the pressure, the higher the material and manufacturing costs of barrel pull-out pumps. This does.Tapping A Stage of A Boiler Feed Pump1. In the case of ring-section pumps, a partial flow at an intermediate pressure can easily be tapped through a tapping nozzle in one of the stage.Balancing of Radial Forces on The Pump RotorRadial forces arise from the weight of the rotor, mechanical unbalance or hydraulic radial thrust. The radial forces are balanced by two oil-lubric.Warming Up and Keeping WarmTransient or low flow operating conditions cause additional loads on boiler feed pumps. This leads to additional stresses and strains as well as to.Inquiry

Classification of Centrifugal Pump - boilersinfo

A pump stage is defined as that portion of a centrifugal pump consisting of one impeller and its associated components. Most centrifugal pumps are single stage pumps, containing only one impeller. A pump containing seven impellers within a single casing would be referred to as a seven-stage pump or, or generally, as a multi-stage pump.
